Letters Pate/nt No. 96,030, dated October` 19, 1869.

corren-Roasrma The Schedule referred to in these Letters Patent and making part of the same.

To all persons to `whom these presents may come:

Be it known that I, CHARLES T. PALMER, of Norwich, of the county of New London,of the State of Connecticut, have made a new and useful invention having reference to Coffee-Roasters; and I do hereby declare the same to be fully described in' the following specification, and represented in the accompanying drawings, in which- Figure l is a top View,

Figure 2, a longitudinal section, and

Figure 3, aV transverse section of a coffee-roaster as provided with the said invention.

In such drawings- A denotes the coffee-roasting drum, arranged within a furnace, B, and upon a long shaft,'C, the coffeeroaster being'applied to the shaft, so as to be capable of -being slid thereon out of and into the heatingchamber of'such furnace. VThe said heating-chamber of the said furnace is furnished with an opening at one end, and with doors a a thereto, such opening being for the passage of the roaster into as well as out ofthe heating-chaniber.

lhe application of thedrum or roaster to the shaft is such, that by revolving the latter, it will put the roaster in rotation within the furnace-chamber.

All this is well known and common to many coffeeroasters -in use. With a coffee-roasting furnace so made, it has been, necessary heretofore to arrest the rotary motion of the roaster, in order to gain access to the contents thereof, for the removal of any part of such for being examined or tested.

My invention or improvement avoids such stoppagev ofthe roaster, and admits of portions of `the coffee or contents beingtaken from it while it may be in revolution, or performing the duty of holding the coffee, and roasting it over the roasting-lire.

In carrying out my invent-ion, I employ what I-term a stationary head, A, to the roaster A, and I provide such head with a test-opening or hole, a', which may havea slider or cover, b, applied to it, to close or-open it, .as occasion may require. This stationary head, I prevent from revolving with the roasting-drum, by means of an arm, c, extended down from thehead into a staple, or against a stationary abutment, or into the narrow space d, between two horizontal and parallel rails e, extending from the furnace 'to the standard f, for supporting the shaft, such rails being arranged in manner as represented.

In the drawings, the head A' is exhibited as a at or circular annulus, arranged within a corresponding opening made in one end of the roasting-drum, and encompassing and disposed conce'ntrically with a smaller and auxiliary circular head ordisk, g, through the central part of which the shaft passes. This latter disk g is connected with the main rotary circular head of the drum, by means of one or'more radial arms, h, extending from one to the other, and arranged inside of the drum.

Within its periphery, the roaster has a supply-opening, Aprovided with a door or cover, t. Y

The rails e e, with the 'arm c,'not only hold the head A stationary while the roasterI may be in revolution, but they admit of the roaster, with the arm, being moved out of and away from the furnace. /When the roaster and arm are so drawn out of the furnace, and the roaster is put in revolution, the railsand arm will still hold they head A stationary.

With the stationary head and the revolvable roaster applied to the shaft, it will be an easy matter at any time, by simply uncovering the opening of the head, to 'extract through such opening, and from the roaster while in operation, 4a portion of the coffee or roasting contents of such roaster.

The stationary head may have a diameter equal 4or about equal to the internal diameter of the roaster, and such head may be a full circle, except in having a shafthole at its centre, in which case the rotary roaster might be supported by a series of radial arms extended from its periphery to'a hub arranged to slide on the shaft, lengthwise of it, but otherwise applied so as to be revolved with the shaft and drum. In this latter case, the head should have the test-opening or tap-hole and the retaining-arm.

I claim, as lmy invention- A coffee-roaster, as made with the stationary head, provided with the retaining-arm and -the tap-hole, as

-set fort-h.

Also, a coffee-roaster, as so constructed, with the stationary'head and the retaining-arm, as explained,

and as having the set of stationary parallel rails e e, or

the equivalent thereof, applied to or arranged with the
